I guess you remember that two months ago I told you about a new version of Clean Server. At that time it was planned for release in September. Well, it was almost on schedule, one week later :), so right now you can download it. There are many improvements on this version, starting with the architecture and ending with the product distribution. I suggest you to read this brochure, as it describes quite nicely the new features and functionality.
Several customers are already running it, one of them with a large infrastructure of Plesk servers. He has around 300 servers, but they didn’t find enough time to upgrade them all. Anyways, they keep upgrading more and more every day and they dedicated several nodes for scanning (last time I checked, they were using five nodes). The results impressed them (funny: before this test they also offered Dr.Web for dedicated servers and VPS, but after the last week they decided to drop it from the offer). The average load on the servers got 40% lower and they did not experience any problems related to local email delivery. Before Clean Server 4, a lot of problems occurred due to email floods.
But I let you test it and build your own feedback.
